What Are the Requirements for PCB Multilayer Board?

Oct 10, 2017

1.The power plane of PCB Board should be close to the ground plane, closely coupled with the ground plane, and arranged below the ground plane. 

2.The signal layer of PCB should be adjacent to the inner layer.

3.Isolating digital circuits from analog circuits.

4.The external interference of the high frequency circuit is larger, so it is better to arrange it separately. The upper and lower layers are transmitted by the intermediate signal layer directly adjacent to the inner layer.
